Chiller

Chillers are refrigeration systems needed to control temperatures accurately and ensureoptimal energy efficiency in many industrial applications. Control of the fan-cooled heat exchanger fans in chillers in turn is of fundamental importance to ensure the stable, long-running functioning of these systems, maximizing performance and reducing operating costs.

All refrigeration systems require accurate management to suit the ambient and operating conditions, and inefficient control could lead toenergy waste, increased costs and reduction of the useful lives of the components.

Selpro solutions were designed to face these challenges, providing advanced management with a high level of customization available for the refrigeration systems. Our technology allows us to maintain condensation temperatures at optimal values. This result can be achieved by accurately setting thepressure setpoint that dynamically adjusts to reflect changes in ambient conditions and the specific requirements of the refrigeration system. Controlling the fans means that the speed can be controlled in proportion to the heating load requirements, avoiding sudden changes in the airflow that could compromise the stability and overall efficiency of the system.

Selpro solutions are also able to implement energy saving modes. When loads are low, like at night, the system will reduce fan speed and/or limit the number of fans in operation, optimizing energy consumption without compromising on system performance.

In order to support this type of advanced management, the system reads the data coming from the temperature and/or pressure sensors already on the machines in real time. Thiscontinuous monitoring allows the condenser to adjust as necessary, ensuring stable operation andfull control of the key settings.

Selpro solutions for chillers provideadvanced prevention functions through the heat protectionand self-diagnosis systems. In the event of anomalies like overheating or exceeding temperature limits, the system will promptly report the problem, reducing down times and enabling rapid, effective action to be taken. Detailed reports facilitate the identification of the reasons behind the malfunctions and allow targeted action to be taken, ensuring operational continuity including in critical conditions.

Selpro devices also improve the duration and resilience of the systems thanks to functions like automatic unblocking in the presence of ice the management of fan redundancy, reliability even in critical conditions, ease of installation and thedependable performance over time.

Plug and Play technology simplifies the integration into existing systems, while the use of certified materials and high quality components ensure that the refrigeration equipment will last for a long time.
